The man police say may have caused a crash that killed two Shenendehowa High School students will not be charged with a crime until results of a blood test come back.

Saratoga County District Attorney James A. Murphy III and the state police issued a joint statement Monday afternoon with an update on their investigation into the crash that killed Chris Stewart and Deanna Rivers.

In a press conference Sunday, state police Capt. Steven James said a breath screening given to Drue immediately after the crash came back positive for alcohol. Those test results, however, are not admissible in court. James said Drue, 22, could face charges of manslaughter or vehicular homicide.

In Monday's statement, however, Murphy and state police say it is still too early in the investigation to charge Drue: "The (state police) investigation continues to determine the specifics as to what occurred Saturday night and what potential charges are available based on a thorough review of the facts and circumstances surrounding eye witness accounts, accident reconstruction reports, and scientific test results."

Drue was treated for minor injuries at Ellis Hospital following the crash and his blood was taken there. The blood will be tested at the state police crime lab in Albany and results will take about 90 days to come back though Murphy said he and state police investigators have requested that the tests be expedited.

Autopsies of Stewart and Rivers were performed Monday at Saratoga Hospital by Dr. Michael Sikirica, a forensic pathologist, but results have not yet been released.

Also in the statement, Murphy and state police urged the public not to go to the crash site to leave any type of memorial because it is unsafe and instead to participate in the memorial site and Shenendehowa High School East.

"The men and women of the NYSP are working hard on this case and have been for the last 36 hours. In short order we will know more. In the meantime, we must do our job, which is to find out specifically what Mr. Drue did and under what circumstances. We will do our job as we always do, professionally and correctly," James said.
